    // Test the transitions between values of the scientific exponent X.
    // For brevity, we avoid testing all possible combinations of P and X. Instead, we test:
    // * All values of P where some X can be affected by rounding. (For float, this is [1, 7].)
    // * P == 25, which is arbitrary.
    // * P == numeric_limits::max_exponent10 + 1. This selects fixed notation for numeric_limits::max(),
    //   so it's the largest interesting value of P.
    // * Finally, we test the transitions around X == P - 1, ensuring that we can recognize every value of X.
